Monitoring using Proxy Design Pattern with Node.js

The Proxy design pattern in Node.js enhances monitoring and performance tracking for distributed systems by creating a proxy object that controls access to the actual service object. It allows for centralized monitoring, logging of requests, and actions before and after sending requests. This approach offers benefits like decoupled code and easier management, but may introduce performance overhead. Implementation involves setting up a service server and creating a proxy class with a monitoring method using JavaScript's built-in Proxy object.
